ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 308,744, dated December2, 1884.

Application filed April 1, 1884. (No model.)

To all whom it may concern Be it known that I, DoMINIoUs BRIX, acit-izen of the United States, and a resident of Geneseo, in the countyof Henry and State ofIllinois, have invented certain new and usefulImprove ments in Roller-Skates; and'I do hereby declare that thefollowing is a full, clear,- and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, refer-- ence being had to the accompanyingdrawings, which form a part of this specification, and in which- Figure1 is a side view of a roller-skate em bodying my improvements. Fig. 2 isa front view of the same, and Fig. 3 is a cross-section through line 000c in Fig. 1.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to roller-skates; and it consists in theimprovements in the same which will be hereinafter more fully described,and particularly pointed out in the claims.

In the accompanying drawings, A denotes a roller-skate 'of any approvedconstruction, having the usual rollers, B. I prefer to construct theserollers with a rubber tire slipped into a groove in the periphery of therollers for the purpose of making them run noiselessly.

Fastened upon the front and back part of the skate, immediately in frontof the front pair of rollers, and back of the hind pair of rollers, is ashort metallic bar, D, the lower end of which has a cross-head, E, whichmay be pivoted and swiveled, at 0, upon the lower end of the bar. Thiscross-head is provided with a rubber roller, F, and, if desired, t hisbar or pendant D may be made in two parts, one screwed into the other,so that the bar may be lengthened or shortened at will.

Fastened to opposite sides of the foot-plate are downwardly andoutwardly projecting arms or outriggers G, at the lower ends of whichare small rubber rollers H, so arranged that these rollers will projectfrom a quarter tohalf an inch outside of the main rollers B, and liftedabout one-fourth of an inch from the lioor or ground. It will be seenthat the moment the ankle bends, so as to tiltthe skate sidewise, theserollers or Outriggers H will touch the floor, and thus prevent the anklefrom being sprained by doubling over. It will also be seen that thefront and rear brakebars, D, will prevent the skate from tipping overforward or backward, and that the operator can come to a sudden stop atany time simply by tipping his skate, so as to bring either one of thebrakes into frictional contact with the floor.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. As an improvement inrollerskates, the Outriggers G G, placed on opposite sides of thefoot-plate between the rollers, and provided with rollers at their outerends, substanti ally as set forth.

2. As an improvement in roller-skates, the brakes consisting of thefront and back bars or pendants, D D, having cross-heads E at theirlower ends, provided with rollers F, sub stantially as set forth.

.3. As an improvement in roller-skates, the brakes consisting of theextensible front and back bars or pendants, D D, arranged respectivelyin front of and back of. the rollers B B, and provided with the hingedor swiveled cross-heads E, having frictional rollers F, substantially asand for the purpose shown and set forth.

4. The improved roller-skate herein shown and described,'providedwiththe outriggers G, having rollers H, and having the front and backbrakes, D, provided with cross-heads E, swiveled at C, and havingfriction-rollers F, the whole constructed and combined substantially asand for the purpose shown and specified.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

DOMINICUS BRIX.
